My invention relates to heaters, and it refers especially to a heater which is adapted for installation in a fireplace.

One object of m invention is to utihze the space at the si es, the to and the rear of-a fireplace, and to secure t erein a heater which is adapted to cause the cold air from the floor level of a'room to flow through the heater, and to be heated by the heating elelo ment inthe fireplace and distributed into the room as hot air above the fireplace and without any liability of mixing the said hot air with smoke'or odors from the heating element.

Another object of the invention is to con.-

struct a fireplace'heater with a large exposure surface to the heat radiations from the heating element in the fireplace so as to maximize the efficiency of the heater.

A further-object is to construct a fireplace heater of a minimum number of parts and to so arrange them that the assembling or disassembling of the heater may be fac litated, and so that the heater can be easlly installed in a fireplace and easily removed therefrom and can not'easily order.

A further object is the provision of a fire place heater that is adapted to surround or encompass the heating element of the fire place, and in existing fireplaces it may be a fuel grate.

A further object of the invention is to construct a fire laceheater of such dimensions and with its parts so arran ed that it will not interfere with the dra t'through the chimney.

A still further object is to make, a fireplace heater which is attractive in its design and will serve as an ornament in any fireplace. Y

Still further objects and advantages will appear from the following detailed description and from the accompanying drawings, which illustrate the preferred embodiment of my invention and in which:

Figure 1 is a front view of the heater installed in a fireplace, certain parts being heater elements together and for removably broken away to show interior construction; Fig. 2 is a transverse vertical section along the line 2--2 of Fig.. 1, and showing to advantage the unobstructed coming and outgoing air indicated by the arrows;

course for the in- Fig. 4 is a plan of one of the lower conduits; and

Fig. 5 is a sectional plan of the heater chamber along the line 5-5of Fig. 2.

With reference to the drawings, the heater of my invention, in use, is illustrated in Fig. 1, and I propose to make heaters of such shapes and dimensions suitablefor installation in ordinary fireplaces '10, whether new or old, and secure them in the fireplaces in such a manner so that they can easily be removed therefrom. For this purpose the heater comprises a pair'of upper air-conduits 11 and a pair of lower air-conduits 12, all of which conduits are open at their front endsand are adapted to extend along the side walls of the fireplace from the front to the rear thereof, as shown in Figs. 1 and 2. The lower conduits may be provided with feet 13 for supporting the heater on the floor of the fireplace.

Each of the lower conduits 12 has an up- I ward turned rear end 14, which is reduced at'the to for receiving thereon one of the lower ends of a manifold chamber 15, and each of the upper conduitsll has a downward turned rear end 16, which is enlarged at the bottom for seating therein one of the upper ends of the said chamber. The rear wall of'the chamber 15 is close to the rear wall of the fireplace, but the ends at 16 are considerably larger than the ends at 14 and extend forward into the fireplace, and the front wall of the chamber 15 thus gradually slants from the bottom outward to the top so as to overhang the grate 17 and effectively receive the heat radiations from the fuel in In addition the front wall may be provided with corrugations 18 to further increase the heating surface and the efficiency of the-heater.

At the front the conduits 11 joint eac other, and the conduits are provided with lugs 19, which are perforated for receiving therein fastening means 20 inorder to secure the said conduits to each other. I

Means are also provided for securing the securing the heater in the fireplace. Such means preferably comprise-two turnbuckles 21 provided with right and left hand threads for engagement with the respectively threaded ends of rods 22. The other ends of the rods are threaded for engagement with assages 'of the upper of the heater, and the plates are preferably flush with the face 28 of the fireplace.

In operation, the hot gases from the burning fuel in the grate 17, impinge chiefly upon the front wall of the manifold chamber and heat the same and thus cause the contained and heated air in the chamber to rise and flow through the upper conduits and into the room. The comparatively cool lower conduits draw in the cool air at the floor of the room as the heated .air issues through the register plates of the upper conduits. In the plan view of Fig. 3 it is seen that the opening 26 allows the products of combustion to easily pass therethrough and into the flue 27 of the chimney.

From the foregoing description taken in connection with the accompanying drawings the advantages of the construction and method of operation will be readily understood by those skilled in the art to which the invention appertains, and while I have described the principle of operation, together with the device which I now consider to be the best embodiment thereof, I

. desire to have it. understood that the device shown is merely illustrative and. that such ehan es may be made, when desired, as fall withln the scope of the appended claims.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent of the United States the following:

1. A heater comprising a heating element, lower air conduits extending longitudinally below and upon each side of said heating element and resting upon the floor in proximity to the side walls of the fireplace, upper lower air conduits extending longitudinally below and upon each side of said heating element and resting upon the. floor in prox-,

imity to the side walls of the fireplace, upper air conduits extending in parallel relation to said lower air conduits above said heating element, a manifold chamber disposed in close proximity to said heating element and connecting the rear ends of said lower and upper air conduits, op ositely disposed threaded bosses upon the ront ends of said upper and lower air conduits and expansible elements extending between the uppergand lower air conduits engaging'alined threaded bosses in order to clamp the front ends .of the lower air conduits to the floor and to clamp the front ends of the upper conduits to the front of the top wall of the fireplace.

In testimony whereof, I aflix my signature.
